Recent Advance in Electrochemical C(sp2)—H Amination of Arenes
Aniline and its derivatives are widely used and consumed in human life and industrial production,which inspires the direct aromatic C(sp2)—N construction from the corresponding C(sp2)—H bond.In recent years,as a controllable,sustainable,ambient,and highly scalable methodology,organic electrochemistry has received greater attention and also combined aromatic C(sp2)—N amination,presenting novel reactions.In this review,the common mechanism manifolds of electrochemical aromatic C(sp2)—H amination reactions are summarized,and the reactions examples are classified according to the type of amine sources.The prospects and challenges in this field are provided.
